Bipolar neurons are commonly found in specialized sensory organs, such as the retina of the eye and the olfactory epithelium in the nose.
A unipolar neuron has a single process that divides into two branches, functioning both as an axon and a dendrite. Multipolar Neuron is the most common type of neuron and has multiple processes extending from the cell body – one axon and two or more dendrites.
Most neurons in the brain and spinal cord are multipolar neurons, and they play a key role in motor control and integration of information. A pseudopolar neuron is a type of sensory neuron with a single process that emerges from the cell body and then splits into two branches, resembling a "T" shape.
